Allow setting scan_res_handler from the callback function

Browse source 
Some new code I'm working on will need the scan_res_handler assigned all
the time in certain circumstances, so the easiest way is to reset it
within the handler. This is currently prevented by the way the code in
the event handler works -- change that to permit such usage.
